i have installed my ingnition box in the trunk andran the wires to the front increasing wire guage as it went, my question is when its in use my car doesnt run right, its at 10 degrees timin before idk what it is after but it idles hard and misses.
someone had suggested to me that you have to unplug the tfi ignition module and the msd box will control everything. is this possible?
any help will be greatly appreciated

 

how do you have it wired?

 

I believe the tfi needs to remain plugged in, mine is and it runs fine

 

tfi needs to be plugged in. its how the computer controls the ignition system. if you dont believe me unplug it, the car wont start.

check to make sure you didnt cross any wires when you did the install

 

its wired fromthe trunk along driver side to engine. i purchased the msd harness that goes inbetween the coil and the wireing harness.
it just dont seem right somehow but i checked the wireing the instructions of all thinks

 

you wired something backwards

 

go through it again and check all wiring!!!
